I need help on my 1.1 quiz

ematics 30-1 Quiz 1.1 - TS Numerical Response 2. Given f(x) = 2x2 - 10, the positive x-value that gives the smallest value of y = f(x), to the nearest hundredth, is Hint: Consider the domain restrictions. 6. The interval for which vx - 1 is nonreal is A. x 1 C. -11 Hint: Recall that for x, x may have two possible values, positive and negative. 7. Determine the solution to 3 = 8 - 2x + 1, and indicate the restrictions on the variable. A. x =- 12, x - B. x =- 12, x 2 N/ - N/- N/- N/- C. x = 12, x 5 D. x = 12, x 2 Hint: Isolate the radical first, then square both sides to solve for x
